Seems conceivable. I remember a friend in high school band camp with a cassette player and a stack of manuscript paper who transcribed a Chicago song by playing a couple seconds of it, writing down all the parts and then playing the next couple seconds. I really wish I'd understood back then that this was a learnable skill. It wasn't until I was in my 30s and had a few years of choral singing under my belt that I began to develop some simulacrum of that ability.
